A person picks up an iron ball on a rope and starts to spin it around them. The person does 500 J of work to get the mass spinning. While spinning, the person steps onto ice (take friction out of the equation). The result is both the mass and the person are spinning around the same point in space (the mass is circling faster on a larger radius and the man is circling slower on a smaller radius). There is a point between the masses that is stationary. The iron ball has a mass of m = 10 kg. The person has a mass of M = 80 kg. 3 vb Point that masses rotate around M Vp When the person lets go of the rope, how fast will the person move and how fast will the ball move?
